If someone doesn’t wear a uniform to school the teacher will point that child out and ask him/her about the reason why he/she has not worn the uniform. If a child has a genuine reason for not wearing the uniform like it was wet, it was dirty, it is the child’s birthday etc then the teacher may let him/her go and tell the child to be careful from the next time. But if the child gives excuses and argues with the teacher then the teacher may send the child out of the class and may take any preferable action against the child.
